Washington (CNN) -- The U.S. Defense Department Thursday released the names of U.S. military personnel killed in Saturday's downing of a helicopter in Afghanistan.

Thirty-eight people were killed in that attack, eight of them Afghan military personnel. It was the single largest loss of life for U.S. troops since the Afghan war began in late 2001.

Of the 30 Americans killed in the helicopter crash, 17 were Navy SEALs.

Twenty-two of the dead were U.S. Navy personnel, the Pentagon said. Fifteen were SEALs belonging to the top-secret unit that conducted the raid that killed al Qaeda leader Osama bin Laden at a compound in Pakistan. Two others were SEALs assigned to a regular Naval special operations unit.

Five were so-called conventional forces with particular specialties who regularly worked with the SEALs.

The other eight U.S. troops killed included three Air Force forward air controllers and five Army helicopter crew members.

NATO said it killed the militants responsible for the attack. Taliban spokesman Zabiullah Mujahid rejected that, saying a NATO airstrike killed a separate group of insurgents.
